[0007] The present invention is further configured such that a second extension portion is fixed to one side of the movable contact piece, and a first extension portion is fixed to the other side of the stationary contact piece.

[0008] By adopting the above technical solution, the provision of the first extension portion and the second extension portion can facilitate the installation of the moving contact piece and the static contact piece.

[0009] The present invention is further configured such that slots are provided on both sides of the inner wall of the mounting hole.

[0010] By adopting the technical scheme, the static contact piece is limited through the clamping slot, so that the static contact piece cannot shake in the clamping slot.

[0011] The utility model further sets up, the top of base is equipped with upper cover, and the both ends of upper cover are fixed first clamping plate and second clamping plate respectively.

[0012] By adopting the technical scheme, the terminal assembly inside the base can be dustproof through the upper cover, and the first clamping plate and the second clamping plate can conveniently limit the upper cover.

[0013] The utility model further sets up, the inside of base, first clamping plate and second clamping plate all are equipped with jack.

[0014] By adopting the technical scheme, the plug can be conveniently inserted through the jack.

[0015] In summary, the utility model mainly has the following beneficial effects:

[0016] The utility model discloses a set up upper cover, movable contact piece, static contact piece and ground wire contact terminal, is equipped with first contact part and second contact part on movable contact piece, improves contact stability when the plug is inserted into the inside of base and contacts first contact part and second contact part, and the contact rod of movable contact piece and contact point movable contact, when the plug is inserted into the inside of base, the contact rod and contact point are disconnected, realize the control of electric property connection, the upper cover can be set up and can be encapsulated metal terminal to the dustproof effect of earphone socket, and when using, can also conveniently dismount upper cover.
